The first aperture may be configured such that the first and second hand of the user, in a two-handed swinging mode, are spatially distributed and oriented along intersecting axes. The grip handle may be configured, in a dumbbell mode, such that the user&#39;s first hand is inserted through the second and third aperture to grip the grip handle at the center of the FRW.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a non-provisional application and claims the benefit of U.S. Application Ser. No. 63/266,509, titled “Multi-Purpose Functional Ruck Weight,” filed by Graham Westbrook, et al., on Jan. 6, 2022.

TECHNICAL FIELD

Various embodiments generally relate to strength training equipment.

BACKGROUND

Weight training is a method for developing strength, increasing the size of skeletal muscles, and maintaining strength. Weight training allows a user to use the force of gravity from weights to oppose the force generated by the user's muscle contraction. Weight training uses various equipment and movement types to target specific muscle groups.

Free weights include dumbbells, barbells, medicine balls, sandbells, and kettlebells. Free weights do not constrain users to fixed movements. Free weight requires more effort from a user's stabilizer muscles. Some free weight exercises can be performed sitting, lying on the ground, and/or using other equipment such as an exercise ball.

Rucking is the action of walking and/or jogging with a weight on your back. Walking with a weighted rucksack and/or backpack is a low-impact exercise. Carrying weight is a typical part of a person's daily routine. Rucking is used commonly in military training, physical conditioning in police forces, and by fitness enthusiasts. For example, in military training, a soldier may carry sandbags while jogging. For example, a soldier may jog in boots and military gear while carrying a weighted rucksack.

SUMMARY

Apparatus and associated methods relate to a multi-purpose functional ruck weight (FRW). The FRW includes a packing mode, a two-handed swinging mode, and a dumbbell mode. The FRW is a weight reflectively mirrored about a bisecting longitudinal axis. The weight includes a top and a bottom surface. The FRW includes a swing handle defined by a first aperture extending through the top and bottom surfaces. The weight may be carried in a rucksack against the user's body in a packing mode. The first aperture may be configured such that the first and second hand of the user, in a two-handed swinging mode, are spatially distributed and oriented along intersecting axes. The grip handle may be configured, in a dumbbell mode, such that the user's first hand is inserted through the second and third aperture to grip the grip handle at the center of the FRW.

Various embodiments may achieve one or more advantages. For example, some embodiments may include a grip handle distal to the swing handle, the grip handle defined by a second aperture and a third aperture extending through the top and bottom surfaces. The FRW includes a major and a minor dimension separated by a thickness to define a spacial envelope. The FRW may, for example, include finger divots. The swing handles of the FRW may, for example, include countours. The grip handle of the FRW may, for example, include contours. The grip handles of the FRW may, for example, include textured grips. The grip handles of the FRW may, for example, include a coated grip. The FRW spacial envelope may, for example, be coated by an external damper such that the external damper absorbs kinetic energy during an impact. The swing handle of the FRW may, for example, include contours to increase the surface area of engagement with the user's hands. The grip handle of the FRW may, for example, include a textured grip to increase the coefficient of friction between the user's hands and the grip handle.

The details of various embodiments are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description, drawings, and claims.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

To aid understanding, this document is organized as follows. First, to help introduce discussion of various embodiments, a use-case system is introduced with reference to FIGS. 1A-1D. Second, that introduction leads to an application of a functional multi-purpose functional ruck weight (FRW) with reference to FIGS. 2-30 of some exemplary exercises. Finally, with reference to FIGS. 31-39 , the FRW various views and exemplary dimensions are illustrated.

FIG. 1A depicts an exemplary multi-purpose functional ruck weight (FRW) employed in illustrative use-case scenarios 100, including a ruck mode; a dumbbell mode; and a two-handed overhand mode. The illustrative use-case scenarios 100 includes a backpacking use-case scenario 105.

The backpacking use-case scenario 105 includes a user 110. The user 110 is wearing a rucksack 115. The rucksack may, for example, include a backpack. In some implementations, the weight may be transported in luggage for travel. The rucksack 115 contains an exemplary FRW 120. In the backpacking use-case scenario 105, the exemplary FRW 120 is aligned with the back of the user 110.

The use-case scenario 100 includes a swing mode exemplary scenario 125. The swing mode exemplary scenario 125 includes a user's hands 110 a. The swing mode exemplary scenario 125 includes a longitudinal axis 120 a bisecting the exemplary FRW 120. The swing mode exemplary scenario 125 includes an axis orthogonal to the longitudinal axis (not shown). The hands 110 a include a user's hands axes 110 b that bisects each hand, configured such that, the hands' axes intersect when grasping the swing handle. The exemplary FRW 120 includes a center of mass of the weight 120 b.

The illustrative use-case scenarios 100 includes a grip handle use-case scenario 130. The grip handle use-case scenario 130 includes a first aperture 135 near the proximal end of the weight. The grip handle use-case scenario 130 includes a second aperture 140. The grip handle use-case scenario 130 includes a third aperture 145. The exemplary FRW 120 includes a handle 150. The second aperture 140 and third aperture 145 allow a user's hand 110 a to grasp the handle 150.

FIG. 1B is a block diagram depicting an exemplary diagram of an exemplary FRW and shows the interaction of a user's hands with the tangent lines of the first aperture. The grip handle use-case scenario 130 includes a proximal end 131 of the FRW. Te grip handle use-case scenario 130 includes a distal end 132 of the FRW. The proximal and distal ends of the weight may be referred to this orientation in all other modes unless otherwise specified. The grip handle use-case scenario 130 in FIG. 1B includes a first tangent line 135 a of the first aperture 135. The grip handle use-case scenario 130 in FIG. 1B includes a second tangent line 135 b of the first aperture 135. The first tangent line 135 a of the first aperture and the second tangent of the first aperture intersect. In a two-handed mode, the user's hands axes 110 b intersect both the first tangent line 135 a and the second tangent line 135 b.

FIG. 1C depicts an exemplary FRW 155 with recesses, finger grips, and attachments. The exemplary FRW 155 includes an exemplary recess 160. By way of example and not limitation, the exemplary recess may be ⅛″ deep. The exemplary recess may be 1/16″ deep. The exemplary recess may be ¼″ deep. The exemplary FRW 155 includes a finger grip 170. The finger grip may, for example, allow a user to grip the distal end of the FRW. The exemplary FRW 155 includes attachments. The attachments may, by way of example, but not in limitation, include nameplates. The attachments, by way of example, but not in limitation, include messages. The attachment, by way of example, but not in limitation, may be phosphorescent. The attachments may, for example, enclose the grip handle. The attachments may, for example, enclose the grip handle to improve the grip, reduce blister formation on a user's hand, and prevent the tearing of the skin when using the weight. The attachment may, for example, include a paracord wrapped along the center grip handle. The attachments may, for example, include a name tag. The attachments may, for example, include a glow-in-the-dark plate with a message depicted. The attachments may, for example, include an American flag. The attachments may, for example, include a Texan flag.

FIG. 1D depicts an array 180 of several embodiments of exemplary FRWs.

The array 180 includes an exemplary FRW 120 c with a fourth aperture. The fourth aperture reflectively mirrors the first aperture along an axis that bisects the center of the plate that is orthogonal to the longitudinal axis. The exemplary FRW 120 c includes a first swing handle, a grip hand, and a second swing handle. A person may, for example, use the exemplary FRW in a rucking mode. A user may, for example, use the exemplary FRW in dumbell mode, such that the user would grip the grip handle to perform extension exercises. A user may, for example, grip a first swing handle near the proximal end of the weight, in a two-handed mode such that, the user may perform swinging exercises while griping the first swing handle by putting their fingers through the first aperture. A user may, for example, grip a second swing handle near the distal end of the weight, in a two-handed mode such that, the user may perform swinging exercises while griping the second swing handle by putting their fingers through the first aperture.

The array 180 includes an exemplary FRW 120 d. The exemplary FRW 120 d includes a curved end near the distal end of the weight. The bottom curvature may, for example, be desirable while rucking, because the curvature may prevent shifting while the ruck rests in the weight.

The array 180 includes an exemplary FRW 120 e. The exemplary FRW 120 e includes a grip handle that is parallel to an axis orthogonal to the longitudinal axis bisecting the weight. A user may, for example, desire to switch the way the user grip's the grip handle for different exercises and muscle extensions.

The array 180 includes an exemplary FRW 120 f. The exemplary FRW 120 f includes a fourth aperture. The fourth aperture is a different size and shape than the first aperture. The fourth aperture may, for example, include a rectangular shape, an oval shape, and/or a circular shape. The first aperture may for example also have various shapes that may, for example, include a rectangular shape, an oval shape, and/or a circular shape.

The array 180 includes an exemplary FRW 120 g. The exemplary FRW 120 g does not include a grip handle. The exemplary FRW includes a first swing handle. The exemplary FRW includes a second swing handle. In some implementations, the second handle may include a rectangular shape, an oval shape, and/or a circular shape.

The array 180 includes an exemplary FRW 120 h. The exemplary FRW 120 h includes an angled grip handle relative to the longitudinal axis. The angled grip handle may, for example, allow a user to perform different extensions and exercises. The angled grip handle may, for example, allow a user to perform the same extension and exercises but target different muscles due to the different hand positioning. The FRW 120 h includes a fourth aperture, which may, for example, include a second swing handle.

The array 180 includes an exemplary FRW 120 i. The exemplary FRW 120 i includes a first rectangular recess near the proximal end of the weight. The first rectangular recess may, for example, be used for a name tag. The exemplary FRW 120 i includes a second rectangular recess. The second rectangular recess may, for example, include an attachment slot for a message.

The array 180 includes an exemplary FRW 120 j. The exemplary FRW 120 j includes a half-hexagonal second and half-hexagonal third aperture. The second and third aperture may, for example, be multisided.

The FRW is, as depicted, a multi-purpose fitness system designed to comfortably fit in a backpack and/or rucksack (e.g., for rucking). The FRW may allow easy access to be removed and used as a customizable apparatus for working out and facilitating weight exercises traditionally. The FRW may, in some examples, provide multiple exercises available to a user who, for example, conducts fitness outdoors. In some implementations, the FRW may include glow-in-the-dark features that make it visible when doing late-night, overnight, and/or early morning workout activities outside.

In some examples, rucking—or hiking with weight—sometimes requires a backpack. For example, the backpack may be a specialized rucksack or a vest in order to intentionally increase the weight of a practitioner. For example, the weight may allow the practitioner to build muscle, lose fat, and/or increase stamina For example, rucking may be easier on the knees than running but adds a level of difficulty to walking.

For example, the FRW may, in some implementations, be substantially 9″×1.375″×15″ in size. For example, the FRW may include an edge handle and/or a center handle. The edge handle may, in some implementations, be located at a top side of the FRW. In some examples, an edge handle may be a Kettlebell handle. In some examples, an edge handle may include an altered chamfered edge. For example, an edge may have a radius that allows a lay-flat feel for the wrist doing overhead exercises (e.g. clean/jerk) without impeding motion. The rounded edge may, for example, also be configured to facilitate one- and/or two-handed swinging motions.

The center handle may, for example, be a dumbbell-like handle. In some implementations, the center handle may have enough room in a cavity for bare hands and/or hands with gloves to conduct curling movements, overhead and/or tri-cep movements, and/or neutral grip movements. For example, a practitioner may perform pushups off of a raised feature using the center handle. For example, the center handle may also be configured to allow the FRW to be held in its center of gravity. In some examples, holding the FRW substantially at its center of gravity may get the most out of its weight for movement. In some embodiments, holding the FRW at/near its center may be used to contribute to a shield-like aesthetic that augments the design aesthetic.

In some implementations, the FRW may include a finger grip: For example, the FRW may include a finger grip on one side and ambidextrous thumb recesses on the other side. In some examples, the finger grip may allow a practitioner to hold the FRW ergonomically while overhead and/or underneath without having to clumsily grab the side of the part without having any purchase. This may, for example, advantageously increase the safety of the FRW by substantially reducing the likelihood of dropping and/or may advantageously support functionality.

In some implementations, the FRW may include thumb recesses on opposite sides of the FRW. For example, the thumb recesses may naturally move the thumbs into a grip-position with the hand curled in a C-like position and fingers holding onto the other side. For example, the thumb recesses may improve safety, ergonomics, and/or functionality.

In some implementations, the FRW may include customizability aesthetic features. For example, the FRW may allow a practitioner to customize the part by adding patches and/or other removably coupled (e.g., hook-and-loop enabled) art to be attached/detached from the plate. For example, the FRW may include a 1″×⅛″ recess on front of part at the top side. For example, the 1″ recess at front-top may be used as a “name tape” which can display a first name, last name, and/or nickname. For example, the FRW may include a 2″×⅛″ recess on front of part at the bottom side. For example, the 2″ recess at front-bottom of the part may be configured as a 2″×3″ decoration to include, for example, flags, morale displays, and/or other atypically-sized patches to be affixed to the part.

In some implementations, the FRW may include a glow technology. For example, the FRW may include glow-resin embedded in at least some portion of the FRW. For example, glow-resin may be embedded as lettering and/or applied as coating for glow-in-the-dark capability. Such embodiments may, for example, advantageously provide visibility during late-night, overnight and/or early morning workouts. For example, a glow resin marine epoxy mix may be poured into certain crevices and/or hardens to become part of the FRW. For example, the FRW may be ‘charged’ with daylight (e.g., natural light), and/or artificial light (e.g., flashlights) to luminesce (e.g., for hours) and so be (more) visible to the naked eye.

In some implementations, the FRW may be weatherproofing. For example, the part may include an exterior coating that makes it waterproof and/or weatherproof to substantially reduce a likelihood of rust. For example, the weatherproofed FRW may be grasped by bare hands and/or with gloves in the rain with slip resistance (e.g., weatherproofing may include a polymeric component). In some examples, the weatherproofed FRW may protect it from the (outdoor) elements (e.g., sun, moisture, oxygen). Weatherproofing may, for example, advantageously provide a safety element (e.g., preventing slipping during exercising and so preventing injury to self and/or bystanders).

For example, the FRW may be substantially 20 lbs. In some embodiments the FRW may be substantially 40 lbs. In some embodiments the FRW may be substantially 60 lbs. In some embodiments the FRW may be more than 60 lbs. In some embodiments the FRW may be less than 20 lbs. In some implementations, two FRWs may be interconnected with a bar to be converted into a barbell. In some implementations, the FRW may be stackable. For example, two or more FRWs may be stacked to be used for sled pull and/or prowler push exercises.

Although an exemplary system has been described with reference to FIGS. 1-39B, other implementations may be deployed in other medical, military, commercial, and/or residential applications. Weights may, for example, be used by physical therapists to aid an athlete recover from an athletic injury. In circumstances, the FRW may, for example, be made of a light weight material and be used for an athlete to recover loss motion from injuries. The FRW may, for example, be used in the military for physical fitness tests. Some military branches have been moving away from standard pushups, situps, and timed running to incorporate weighted exercises. The FRW may, for example, be incorporated as a weighted exercise in a military standard fitness test.

The FRW may, for example, be used in commercial settings. A user may, for example, find transporting traditional dumbells over long distances or over plane difficult. However, the FRW allows for fast and compact travel as the FRW can be stored in a ruck, carryon bag, and or a backpack.

The FRW may, for example, be used in residential applications. The FRW may, for example, be used as a weighted set in a residential apartment gym complex. Group exercises with trained instructors may, for example, carryout exercises with the FRW. The instructors using the FRW may, for example, be recorded and be posted online as a video recording and/or audio recording directing exercises with the FRW. Workout calendars may, for example, may incorporate the FRW into a person's physical fitness routine and/or training regiment.

A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made. For example, advantageous results may be achieved if the steps of the disclosed techniques were performed in a different sequence, or if components of the disclosed systems were combined in a different manner, or if the components were supplemented with other components. Accordingly, other implementations are contemplated.
